Embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
A kind of fuel filter lid device for detecting sealability, referring to Fig. 2, including workbench 1, is fixed on workbench 1
Stent 2, stent 2 is frame-type structure, is disposed with its supporting leg towards the aspect of workbench 1 parallel with 1 table top of workbench
Second cross beam 22 and first crossbeam 21, side of the stent 2 away from workbench are fixed with compressed air source unit 3, in the present embodiment, source of the gas dress
Put 3 and use air engine.It is fixed with first crossbeam 21 and is used to support fuel filter lid 8 and toward the jet of jet in lid 8
Mechanism 4, it is connected with compressed air source unit 3 by pipe fitting.Jet mechanism 4 is corresponded on second cross beam 22 and is provided with and is used for lid
8 are pressed on the hold-down mechanism 5 in jet mechanism 4.Lid 8 is sleeved in jet mechanism 4 and is fixed with hold-down mechanism 5, in lid 8
It is upper fall suitable quantity of water, and by compressed air source unit 3 toward inflating in jet mechanism 4.Lid 8 is discoid, and coaxial welding has oil pipe thereon
Interface 9, therefore, the quality of circular weld 10 influence 8 leakproofness of lid.Gas in jet mechanism 4 rushes at lid 8, if weld seam
Had the gap in 10, bubble occurs in the water on lid 8, judge that leakproofness is more directly perceived accurate with this.
To improve the work efficiency of detection device, two group of first horizontal stroke is set along 1 length direction of workbench on 2 supporting leg of stent
Beam 21 and second cross beam 22, are provided with multiple jet plane on every group of first crossbeam 21 and second cross beam 22 along its length respectively
Structure 4 and hold-down mechanism 5, jet mechanism 4 and hold-down mechanism 5 correspond, and each jet mechanism 4 passes through pipe with compressed air source unit 3
Part connects.So as to which detection device can be detected work to lid 8 in batches.
Since lid 8 is discoid, for that can be bonded with lid 8 closely, jet mechanism 4 includes being axially perpendicular to workbench 1
The cylindrical housings 41 being fixed on first crossbeam 21 of table top, housing 41 are hollow, and passage is left for gas circulation.Housing
The air inlet 42 of 41 inner cavity of connection housing is offered on 41 side walls, air inlet 42 is connected by pipe fitting with compressed air source unit 3, air inlet
The air valve 43 for controlling air-flow break-make is provided with 42 pipe fittings being connected with compressed air source unit 3, so as to be controlled by air valve 43
Whether system need not open and close compressed air source unit 3 toward inflating in jet mechanism 4, operate more simple and fast.
In the present embodiment, for hold-down mechanism 5 using the pneumatic cylinder connected with compressed air source unit 3 by pipe fitting, it is fixed on second
On crossbeam 22 and piston rod is coaxially disposed with the housing 41 on first crossbeam 21, so as to work as air pressure cylinder working, props up jet plane
During lid 8 on structure 4, piston rod can be more stably pressed on the tubing interface 9 of lid 8.
Jet mechanism constantly places lid 8 in 4 top and is compacted mechanism 5 and compresses, and 4 top of jet mechanism is gradually worn out,
When serious wear, it may can not be bonded with lid 8 closely, so as to cause gas leakage, influence sealing propertytest result.Therefore, such as
Shown in Fig. 3, the first bearing 411 and the second bearing 412 that housing 41 is arranged to be threadedly coupled, the first bearing 411 and second
Seat 412 is hollow circular cylinder and axis is each perpendicular to 1 table top of workbench.First bearing 411 is welded on first crossbeam 21, the
Two bearings 412 are detachable.So as to which the second bearing 412 can be replaced upon wear, increase the service life of detection device.
Cause 8 poor sealing of lid due to being that whether weld seam 10 is defective in detection lid 8, the second bearing 412
Internal diameter is more than the outside diameter of weld seam 10 and is less than 8 outside diameter of lid, so as to ensure that all weld seams 10 are all detected, improves testing result
Accuracy.
To improve the leakproofness between 8 and second bearing 412 of lid, to ensure that air-flow blows to lid 8 rather than from lid 8
Leaked with 412 junction of the second bearing, therefore, sealing ring 7 is set in 412 top inner cavity of the second bearing, is played to 8 He of lid
The sealing function on 412 top of the second bearing.The lip of sealing ring 7 is against on 412 top end face of the second bearing, so as to work as lid 8
When being pressed on sealing ring 7, sealing ring 7 is not fallen out into 412 inner cavity of the second bearing.Meanwhile in 412 top of the second bearing week
To the outer 6 that is used for coordinating with 8 side wall of lid is set so that when lid 8 is set on the second bearing 412,8 side wall of lid and
Outer 6 fits, and further improves the leakproofness between 8 and second bearing of lid, 412 top.
To reduce the abrasion on 412 top of the second bearing, 7 top of sealing ring is set above on second bearing 412
The outer 6 so that when lid 8 is pressed on second bearing 412, lid 8 is abutted with sealing ring 7, sealing ring 7
Elasticity help mitigate abrasion of the lid 8 to the second bearing 412.
The operation principle and beneficial effect of the present embodiment are：
Lid 8 is set in 412 top of the second bearing, starts the such as air engine of compressed air source unit 3, is supplied to whole detection device
Pressed gas is answered, starts pneumatic cylinder, piston rod movement to 9 top of tubing interface on compression lid 8.Pour, will spray on toward lid 8
Air valve 43 at 4 air inlet 42 of mechanism of qi structure is opened, so that pressed gas enters jet mechanism 4, and impacts 4 top of jet mechanism
Lid 8.Whether there is bubble in observation water to judge whether 8 leakproofness of lid is good, visual result, accurate, False Rate is low.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
